There are many shareware appplications with generously long free trials which will convert WMV to MOV file formats. As for Quicktime plugins, I found this: http://www.flip4mac.com/wmv.htm. I don't think there is anything free out there, though, unless it's open-source._________________Mac Mini 1.25 Ghz, 512 Mb RAM

I've got the trial version of the Flip4Mac WMV Player installed. The website says that Tiger support is coming soon but it seems to work just fine with Tiger on mine. This is exactly what I was looking for._________________2.0GHz Intel Core 2 Duo
